How to: WiFi Cables & Connector Tutorial For What To Use And When


hi guys this is Raul from simple Wi-Fi

make sure you like this video subscribe

to our YouTube channel you can also

comment down below any questions I try

to answer every single one as they come

so in this video we're we talking about

Wi-Fi connect your names types gender

and even polarity so really get pretty

specific on Wi-Fi connectors and then

we're going to jump into Wi-Fi cables so

make sure that you know what to do when

you're choosing your Wi-Fi connections

so let's go so the first thing we were

to jump into is a naming of connectors

we're gonna have the type the gender and

polarity expressed whenever you see a

connector types will be n type SMA TNC


f-type gender will have female male and

then polarity will be expressed only if

the pin is reverse so we're gonna dive

into each three of these sections in

more detail so it's worth noting that

these connector types are typical in the

Wi-Fi world sometimes you see these in

cellular and TV and stuff like that but

for outdoor Wi-Fi antennas you're gonna

always use an outdoor rated n type so n

female or in male on your routers or USB

adapters you're typically gonna see an

SMA which is a little gold connector

it's a lot smaller and sometimes you can

come come across a TNC type or an F type

TNC was popular with the old Linksys

routers and f-type is just kind of that

TV stuff that kind of crosses over

sometimes so looking at a gender now the

way you can tell whether you have a male

or a female if you look in the left side

the male has a threads on the inside and

also a center pin while the female part

of the connector has a threads expose on

the outside so now jumping into the most

confusing part about connectors which is

polarity this typically only applies to

SMA connectors which are indoor

connections as you can see on the right

the antenna has an SMA male because the

threads are on the inside and the router

has an SMA female because the threads


however the pin is on the female as you

can see there it's actually reversed

right so you have an SMA male or female

reverse polarity the RP is shown to

imply that the pin is on the opposite

gender now moving on to how to pick a

cable this is an often overlooked

important part of your Wi-Fi setup step

one is gonna be the length you always

want to go with the shortest length

possible for your cable run and this is

because of signal loss or attenuation

the longer the cable the more signal you

will lose between the antenna and the

radio step two is a type of cable or

really the thickness of the cable you

always want to go with a thickest cable

possible that your budget allows a

thicker cable will just have more

insulating jacket for the RF on your

cable run so for cable runs less than 10

feet you can get by with an L 195 cable

this is the cable typically used as

pigtails on antennas before you can go

on to thicker connections for longer

runs the next step up is the L 240 cable

which is the best cost to performance

ratio for runs up to 20 feet anything

more than that you definitely want to

upgrade to the next step that step being

the L 400 cable which is much thicker

than the cables mentioned before and is

good for runs between 20 and 100 feet

with minimal RF loss at longer cable run

now moving on to typical Wi-Fi cable

configurations first we're going to look

at an outdoor Wi-Fi setup if you have an

outdoor Wi-Fi antenna chances are that

it has an end female built on to it best

of threads are exposed almost all

outdoor rated Wi-Fi antennas have this

type of connectors and end female inside

your USB adapter or your router will

have an SMA female RP that is if the

antennas are detachable on your Wi-Fi

device so your cable assembly will be an

N male with an SMA male RP that is your

cable assembly which will connect to the

outdoor antenna and your indoor Wi-Fi

device looking now at indoor Wi-Fi

antennas you have to make sure that the

indoor device whether that be a USB

adapter or a router has antennas that

come off so they can put a bigger one on

it that bigger antenna will have an SMA

male RP so that I can connect to the

devices SMA female RP in summary your

outdoor Wi-Fi cable should be an N male

2 an SMA male RP and if you're doing an

indoor connection SMA female RP on the

device an SMA may RP on the antenna

you're trying to attach and lastly there

is no way to connect an ethernet cable

to a coax and vice versa

and also with USB or coax a Wi-Fi cable

can now plug into any of these ports on

your Wi-Fi device thanks for watching if
